Abstract
A device for grounding a rotor carrier is arranged inside of a grounded housing and includes a rotatable rotor carrier extending in an axial direction, a grounding device, and at least one bearing. The rotor carrier is supported by the at least one bearing. The grounding device is arranged on a housing arm next to the bearing and includes an electrically conductive annular carrier element with a central cut out. The carrier element forms a permanent electrically conductive connection to the housing arm at an inside surface of the carrier element. An electrically conductive sliding contact extends radially outward and forms an electrically conductive connection to the rotor carrier at an outer lateral surface of the sliding contact. By way of the sliding contact and the carrier element, an electrical connection is established between the rotor carrier and the housing.
